Each piece of content you add to the knowledge base is stored under a named source. Sources help you organize your agent's knowledge into logical groups and manage them independently -- update one source without affecting others.
Navigate to your agent from the My Agents page and open the knowledge base section. You will see:
Each source represents a single content upload, Prompt Builder save, or AI Generate save. For example, you might see:
| Source Name | Chunks | Added |
|---|---|---|
| Company FAQ | 12 | Feb 28, 2026 |
| Refund Policy | 3 | Mar 1, 2026 |
| Agent Prompt - Maya | 8 | Mar 2, 2026 |
| Product Catalog | 15 | Mar 3, 2026 |
To remove a source you no longer need:
Deleting a source removes all chunks associated with it. This action cannot be undone -- if you need the content again, you will have to re-upload it.
Tip: Before deleting a source, consider whether the information has been superseded or is simply outdated. If your pricing changed, delete the old "Pricing" source and upload a new one with current prices. Keeping both old and new pricing sources will confuse the agent.
If you run multiple agents (e.g., a Receptionist and a Customer Support agent), you can share knowledge between them rather than uploading the same content twice.
How to copy:
What happens during a copy:
Common use cases for copying:
Keep sources focused. Each source should cover a single topic. "Company FAQ" is better than "Everything About Our Company" because you can update or replace individual topics without touching others.
Use descriptive names. Name sources so they are immediately recognizable. Include version or date info when relevant: "Pricing v2 - March 2026" is better than "Pricing".
Review regularly. Set a reminder to review your knowledge base monthly. Remove sources with outdated information and add new content for recent changes to your business.
Check chunk counts. If a source has only 1-2 chunks, it may be too brief to be useful. If it has 50+ chunks, consider splitting it into multiple focused sources for better organization.
Remove before replacing. When updating a source (e.g., new pricing), delete the old source first, then upload the new content. Having both old and new versions active simultaneously will produce inconsistent agent responses.
There is no hard limit on the number of sources or total chunks per agent instance. The vector search efficiently retrieves the most relevant content regardless of total knowledge base size. However, a well-organized knowledge base with 5-15 focused sources typically produces better results than a single massive upload.
